Pulling power drops significantly per each millimeter of spacing. Note that every additional insulation layer (e.g., contamination, paint, rust) strongly reduces the pull force. Magnets operate optimally during direct contact; gap nullifies the power. Notice how rapidly the pull force plummet, when the magnet does not touch flatly to the steel surface. When planning the assembly, avoid additional spacers.

The following data calculates the theoretical shear load needed to initiate the sliding of the magnet downwards on a upright metal surface (assuming typical friction). This value is a function of the gap size between the magnet and the surface.

Table 3: Vertical assembly (sliding) - vertical pull
MPL 20x3x2 / N38

Surface type	Friction coefficient / % Mocy	Max load (kg/lbs/g/N)
Raw steel	µ = 0.3 30% Nominalnej Siły	0.70 kg / 1.54 lbs 699.0 g / 6.9 N
Painted steel (standard)	µ = 0.2 20% Nominalnej Siły	0.47 kg / 1.03 lbs 466.0 g / 4.6 N
Oily/slippery steel	µ = 0.1 10% Nominalnej Siły	0.23 kg / 0.51 lbs 233.0 g / 2.3 N
Magnet with anti-slip rubber	µ = 0.5 50% Nominalnej Siły	1.17 kg / 2.57 lbs 1165.0 g / 11.4 N

When mounting a magnet on a vertical plane (e.g., a fridge), it will only hold just approx. 1/5 of nominal attraction strength. Gravity and a weak degree of grip influence the fact that holders slip faster than they detach. Designing a vertical fastening? Consider that the sliding force is significantly lower than the perpendicular breakaway force. On a painted metal, the holder will give way down under a significantly smaller load. Utilizing a rubberized coating can effectively raise the stability.

12 mm	100%	2.33 kg / 5.14 lbs 2330.0 g / 22.9 N

A thin metal plate is incapable of take in the full magnetic flux, which squanders power of the magnet. If you attach a powerful product to a thin surface, the magnetism will pass right through and the holding will be smaller. To utilize the maximum of this neodymium's power, you require a sufficiently solid piece of metal. The saturation effect means that on sheet metal structures (e.g., thin profiles), the holder holds weaker. We advise picking the steel thickness based on the following data.

Standard neodymium magnets irreversibly lose parameters past the thermal threshold. Avoid high temperatures – high temperature can irreversibly damage this magnet. With every degree above norm, the neodymium's force briefly decreases. Avoid using this product in hot environments higher than its working range. Exceeding the critical threshold will result in permanent loss of magnetic properties.

*Important note: Heat tolerance depends not only on the material grade, but also on the magnet's shape. Flat magnets (pancake types) are more susceptible to demagnetization sooner than taller cylinders. Warning indicator in the table indicates permanent field degradation for this particular item.

Two magnetic products interact from a much further distance than a magnet and sheet setup. The setup of magnet-to-magnet generates a stronger field and a larger range of operation. Planning to create a strong closure? Apply two magnets instead of one magnet and a steel. Remember that when connecting a pair of magnets, the pinch force is extreme. The levitation is marginally weaker than the attraction, but still significant.
*Flux density for N-N configuration reaches ~0 Gs in the exact middle between the magnets (caused by magnetic field nullification).
Important: Results show shear force of dual same magnets (friction coefficient ~0.15 for Ni-Ni plating).

Powerful magnet radiation is a large risk to electronics as well as medical implants. These NdFeB products produce a field that prevents correct functioning of sensitive medical devices. Remember: the invisible magnetic field penetrates the body and housings. Increased vigilance must be exercised by people with cochlear implants and drug dispensers. Also at risk are: automatic timepieces, car keys, membranes, and displays. Do not place the magnet near cards, HDD media, or sensitive navigation tools.

Table 8: Collisions (kinetic energy) - warning
MPL 20x3x2 / N38

Start from (mm)	Speed (km/h)	Energy (J)
10 mm	51.34 km/h (14.26 m/s)	0.09 J

100 mm	162.27 km/h (45.08 m/s)	0.91 J

NdFeB products are delicate – a strong collision with metal causes immediate chipping. Control the attraction moment – a neodymium left loose speeds with massive force. Kinetic force can cause material chips or dangerous crushing to fingers. Always hold the magnet during installation so it doesn't hit with great force against the metal. A contact at a velocity of dozens of km/h means shattering of the neodymium. Wear safety glasses when working with powerful specimens.

Warning: This magnet has a standard nickel coating. After use in water, it must be dried and maintained immediately, otherwise it will rust!

Contrary to myths, water does not block the magnetic field. Buoyancy helps in lifting finds.

1. Wall mount (shear)

*Note: On a vertical surface, the magnet holds merely a fraction of its nominal pull.

2. Efficiency vs thickness

*Thin steel (e.g. computer case) significantly weakens the holding force.

3. Temperature resistance

*For standard magnets, the safety limit is 80°C.

4. Demagnetization curve and operating point (B-H)

chart generated for the permeance coefficient P_c (Permeance Coefficient) = 0.32

This simulation demonstrates the magnetic stability of the selected magnet under specific geometric conditions. The solid red line represents the demagnetization curve (material potential), while the dashed blue line is the load line based on the magnet's geometry. The P_c (Permeance Coefficient), also known as the load line slope, is a dimensionless value that describes the relationship between the magnet's shape and its magnetic stability. The intersection of these two lines (the black dot) is the operating point — it determines the actual magnetic flux density generated by the magnet in this specific configuration. A higher P_c value means the magnet is more 'slender' (tall relative to its area), resulting in a higher operating point and better resistance to irreversible demagnetization caused by external fields or temperature. A value of 0.42 is relatively low (typical for flat magnets), meaning the operating point is closer to the 'knee' of the curve — caution is advised when operating at temperatures near the maximum limit to avoid strength loss.

This product is an extremely strong plate magnet made of NdFeB material, which, with dimensions of 20x3x2 mm and a weight of 0.9 g, guarantees premium class connection. This magnetic block with a force of 22.90 N is ready for shipment in 24h, allowing for rapid realization of your project. The durable anti-corrosion layer ensures a long lifespan in a dry environment, protecting the core from oxidation.

The key to success is sliding the magnets along their largest connection plane (using e.g., the edge of a table), which is easier than trying to tear them apart directly. Watch your fingers! Magnets with a force of 2.33 kg can pinch very hard and cause hematomas. Never use metal tools for prying, as the brittle NdFeB material may chip and damage your eyes.

Plate magnets MPL 20x3x2 / N38 are the foundation for many industrial devices, such as filters catching filings and linear motors. They work great as fasteners under tiles, wood, or glass. Their rectangular shape facilitates precise gluing into milled sockets in wood or plastic.

Cyanoacrylate glues (super glue type) are good only for small magnets; for larger plates, we recommend resins. Double-sided tape cushions vibrations, which is an advantage when mounting in moving elements. Remember to clean and degrease the magnet surface before gluing, which significantly increases the adhesion of the glue to the nickel coating.

Standardly, the MPL 20x3x2 / N38 model is magnetized axially (dimension 2 mm), which means that the N and S poles are located on its largest, flat surfaces. In practice, this means that this magnet has the greatest attraction force on its main planes (20x3 mm), which is ideal for flat mounting. This is the most popular configuration for block magnets used in separators and holders.

The presented product is a neodymium magnet with precisely defined parameters: 20 mm (length), 3 mm (width), and 2 mm (thickness). It is a magnetic block with dimensions 20x3x2 mm and a self-weight of 0.9 g, ready to work at temperatures up to 80°C. The protective [NiCuNi] coating secures the magnet against corrosion.

Pros and cons of Nd₂Fe₁₄B magnets.

Strengths

Besides their immense magnetic power, neodymium magnets offer the following advantages:

They virtually do not lose power, because even after ten years the decline in efficiency is only ~1% (according to literature),
Magnets effectively protect themselves against loss of magnetization caused by foreign field sources,
In other words, due to the reflective finish of silver, the element is aesthetically pleasing,
Magnets have exceptionally strong magnetic induction on the outer layer,
Due to their durability and thermal resistance, neodymium magnets can operate (depending on the shape) even at high temperatures reaching 230°C or more...
Due to the possibility of free forming and customization to unique requirements, NdFeB magnets can be manufactured in a wide range of shapes and sizes, which makes them more universal,
Versatile presence in modern industrial fields – they find application in HDD drives, brushless drives, advanced medical instruments, and complex engineering applications.
Relatively small size with high pulling force – neodymium magnets offer strong magnetic field in compact dimensions, which makes them useful in compact constructions

Weaknesses

Disadvantages of NdFeB magnets:

To avoid cracks upon strong impacts, we suggest using special steel housings. Such a solution secures the magnet and simultaneously improves its durability.
When exposed to high temperature, neodymium magnets experience a drop in power. Often, when the temperature exceeds 80°C, their power decreases (depending on the size and shape of the magnet). For those who need magnets for extreme conditions, we offer [AH] versions withstanding up to 230°C
Magnets exposed to a humid environment can rust. Therefore when using outdoors, we advise using waterproof magnets made of rubber, plastic or other material protecting against moisture
We suggest cover - magnetic holder, due to difficulties in realizing nuts inside the magnet and complicated forms.
Potential hazard related to microscopic parts of magnets can be dangerous, in case of ingestion, which is particularly important in the context of child health protection. It is also worth noting that tiny parts of these products are able to complicate diagnosis medical in case of swallowing.
Higher cost of purchase is one of the disadvantages compared to ceramic magnets, especially in budget applications

Pull force analysis

Maximum lifting force for a neodymium magnet – what affects it?

The specified lifting capacity refers to the peak performance, obtained under ideal test conditions, specifically:

with the application of a yoke made of special test steel, guaranteeing full magnetic saturation
whose transverse dimension reaches at least 10 mm
characterized by smoothness
without any clearance between the magnet and steel
under axial force direction (90-degree angle)
at standard ambient temperature

Impact of factors on magnetic holding capacity in practice

During everyday use, the actual holding force is determined by many variables, presented from most significant:

Clearance – existence of any layer (paint, tape, air) acts as an insulator, which lowers capacity rapidly (even by 50% at 0.5 mm).
Pull-off angle – remember that the magnet holds strongest perpendicularly. Under sliding down, the capacity drops significantly, often to levels of 20-30% of the maximum value.
Element thickness – for full efficiency, the steel must be sufficiently thick. Thin sheet limits the lifting capacity (the magnet "punches through" it).
Plate material – low-carbon steel attracts best. Alloy steels reduce magnetic permeability and lifting capacity.
Surface structure – the more even the plate, the better the adhesion and higher the lifting capacity. Roughness creates an air distance.
Thermal factor – high temperature weakens magnetic field. Exceeding the limit temperature can permanently damage the magnet.

Lifting capacity testing was performed on plates with a smooth surface of suitable thickness, under perpendicular forces, in contrast under shearing force the load capacity is reduced by as much as fivefold. In addition, even a minimal clearance between the magnet’s surface and the plate decreases the load capacity.

Warnings

Danger to the youngest

NdFeB magnets are not suitable for play. Eating multiple magnets can lead to them attracting across intestines, which constitutes a critical condition and necessitates immediate surgery.

GPS and phone interference

Navigation devices and smartphones are extremely susceptible to magnetism. Direct contact with a powerful NdFeB magnet can decalibrate the sensors in your phone.

Sensitization to coating

Some people suffer from a hypersensitivity to Ni, which is the standard coating for NdFeB magnets. Extended handling might lead to an allergic reaction. It is best to wear safety gloves.

Hand protection

Danger of trauma: The attraction force is so great that it can result in hematomas, pinching, and broken bones. Protective gloves are recommended.

Maximum temperature

Watch the temperature. Heating the magnet above 80 degrees Celsius will destroy its properties and strength.

Warning for heart patients

Warning for patients: Powerful magnets affect medical devices. Keep minimum 30 cm distance or request help to work with the magnets.

Magnet fragility

Neodymium magnets are ceramic materials, meaning they are fragile like glass. Collision of two magnets leads to them cracking into shards.

Threat to electronics

Powerful magnetic fields can erase data on credit cards, hard drives, and other magnetic media. Maintain a gap of min. 10 cm.

Conscious usage

Handle magnets consciously. Their huge power can surprise even experienced users. Be vigilant and do not underestimate their power.

Dust is flammable

Dust produced during grinding of magnets is flammable. Avoid drilling into magnets unless you are an expert.

Caution! Learn more about risks in the article: Magnet Safety Guide.
